Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes

A hash turns any input into a fixed-length fingerprint, useful for verifying integrity, building cache keys, or comparing values without storing the original. This hash generator computes MD5, SHA-1, SHA-256, and SHA-512 digests from any text you paste, giving you all the common algorithms in one place.

How it works

Type or paste your text and the tool hashes it in your browser using the Web Crypto API and well-tested JavaScript implementations. Output appears as a hexadecimal digest that updates as you edit the input. Nothing is transmitted to a server, so you can hash configuration snippets or identifiers privately.

Common use cases

• Verify a downloaded file's checksum against a published SHA-256 value.
• Generate deterministic cache keys or ETags.
• Compare two strings for equality without revealing them.
• Create short fingerprints for deduplication.

For password storage you should use a slow, salted algorithm instead, so try the Bcrypt Generator. To encode binary data as text, use Base64 Encode / Decode, and for unique identifiers reach for the UUID Generator.

Private by design

All hashing runs client-side, so your input never leaves your machine, with no upload, no logging, and no account required. The hash generator is free and works in any modern desktop or mobile browser.
